Define Variables in Log4j

we Have WebSphere running multiple JVM servers; each JVM has their log file system directory for log4j logging we can configure path as follows.

Define variables in log4j.properties as below.




1)

log4j.appender.logFileAudit.File=/var/logs/${server.name}/application.log







2)

Set the variable server.name in the JVM arguments. For WebSphere update server.xml




<jvmEntries debugArgs="-Dcom.ibm.ws.classloader.j9enabled=true -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=7777" debugMode="false" disableJIT="false" genericJvmArguments="-Xquickstart -Dserver.name=server1"…




to configure above go to 







Application servers > server1 > Process definition > Java Virtual Machine

add Generic JVM arguments with value .....        

-Dserver.name=server1
